Question

The equation for the formation of water from hydrogen gas and oxygen gas is 2H2+O2→2H2O.

How many grams of water can be made from 160 g of oxygen gas?



160 g

180 g

320 g

405 g

Answer 1

180g

Step-by-step explanation:

H:1 O:16

2H2+O2 → 2H2O

2 2(16) 2(1)+(16)

32 18

Now,

32g of O → 2(18)g of H2O

160g of O → 2(18)g divides by 32g times 160g

=180g
